Monotone unitary families

Daniel Grieser

A unitary family is a family of unitary operators $U (x)$ acting on a finite dimensional hermitian vector space, depending analytically on a real parameter $x$ . It is monotone if $\…

Asymptotics of eigenfunctions on plane domains

Daniel Grieser, David Jerison

We consider a family of domains $(Ω_{N})_{N > 0}$ obtained by attaching an $N \times 1$ rectangle to a fixed set $Ω_{0} = {(x, y) : 0 < y < 1, - ϕ (y) < x < 0}$ , for a Lipschitz function $ϕ \geq 0$ .…
